Un dispositivo electrónico, en particular un regulador de alternador, que comprende una etapa de potencia para conectarse a una carga inductiva (L), en particular un inductor de alternador, que comprende al menos un primer par de transistores de potencia (TH1, TH2) conectados a un terminal de un bus DC (+), y un circuito de control (240) para estos transistores, estando dispuestos los transistores en paralelo entre dicho terminal del bus DC y una primera salida (230) a conectar a la carga, al menos un diodo flyback (DL1 , DL2) conectando el terminal opuesto del bus de CC a la primera salida, estando diseñado el circuito de control para generar una señal de control pulsada (241) para regular la corriente en la carga y para detectar una falla de uno de los transistores, el control circuito diseñado, durante el funcionamiento normal, en ausencia de fallo de los transistores, para enviar una señal de control a uno de los transistores (TH1) del primer par, manteniendo el otro transistor (TH2) de este par en estado bloqueado. estado. (Traducción automática con Google Translate, sin valor legal) An electronic device, in particular an alternator regulator, comprising a power stage to be connected to an inductive load, in particular to an alternator inductor, comprising at least one first pair of power transistors connected to a terminal of a DC bus, and a control circuit for said transistors, the transistors being disposed in parallel between said terminal of the DC bus and a first output to be connected to the load, at least one flyback diode connecting the opposite terminal of the DC bus to the first output, the control circuit being designed to generate a pulsed control signal for regulating the current in the load and for detecting a failure of one of the transistors, the control circuit being designed, during normal operation, to send the control signal to one of the transistors of the first pair, while maintaining the other transistor of said pair in an off-state.
